Slight hum in speakers in new setup...fix?

Recommended Posts

Hey all,

 

I just got my new system hooked up: Denon 4500h, Emotiva XPA-5 Gen3, 11 speakers - no sub yet. 

I have the 3 front speakers + 2 surrounds coming from the amp, the rest are hooked up through the AVR.

 

I'm watching game of thrones streaming through laptop -> chromecast and noticed a slight hum the the 2 surround speakers (rp - 500's). Only noticeable if there is a quiet scene and year head is next to the speaker. The front speakers have no hum I can hear.

 

Any ideas what is going on?

 

Thanks,

Spencer

Is it a low frequency hum or high frequency hiss?

Low frequency him would be a ground loop.  Try a different outlet for your receiver and/or amp.  Are you using shielded RCA cables?

If it's a high frequency hiss, very common with Klipsch due to their high sensitivity rating.

I think it's more of the high frequency hiss because it comes out of the tweeter. I can't hear anything coming from the copper cone in the speaker...

Of course this is when my ear is right up on the speaker, but when I move a foot away I can't hear it. Obviously not a realistic scenario but you know us audiophiles! ;)

Thanks for the help @wuzzzer
